I got 2 partition I want to mount

sdb1 which uses ext2 file system sdc1 which uses ext4 file system

I added this 2 line on fstab

/dev/sdb1 /home2 auto auto,noatime,default 0 0 /dev/sdc1 /home3 auto auto,noatime,noload,data=ordered,commit=10,default 0 0

Looks like it's not correct because I fail to mount. How to correct it?

Yet I can't mount them due to some error.

This is my fstab and some command to show that

  • please give the output of dmesg | tail when you try to mount Commented Jan 9, 2013 at 16:34
  • And what is at the end of the kernel logs (just use the exact command mount is suggesting) after the failed mounts? Commented Jan 9, 2013 at 16:35

Reset to default

Try this:

/dev/sdb1 /home2 ext2 auto,noatime,defaults 0 0 /dev/sdc1 /home3 ext4 auto,noatime,noload,data=ordered,commit=10,defaults 0 0

'auto' (as you originally had it in your /etc/fstab entries) is not a valid filesystem type.

  • auto is a special filesystem-type, but that is intended for other filesystems (man mount to see details afaik). Commented Jan 9, 2013 at 22:09
  • Not in the various man fstab pages that I am aware of. Commented Jan 10, 2013 at 1:32
  • no mdpc. It should be auto. And it's working now. Commented Jan 10, 2013 at 2:32
  • From man mount on CentOS5: The auto type may be useful for user-mounted floppies. Creating a file /etc/filesystems can be useful to change the probe order (e.g., to try vfat before msdos or ext3 before ext2) or if you use a kernel module autoloader. Warning: the probing uses a heuristic (the presence of appropriate ‘magic’), and could recognize the wrong filesystem type, possibly with catastrophic consequences. If your data is valuable, don’t ask mount to guess. Commented Jan 10, 2013 at 20:21
  • The last statement however says it all... Commented Jan 10, 2013 at 20:23

I wonder if I should delete this question. The problem is I use default while I should have written defaults. It's too localized I guess.

    too localized gets my vote. Commented Jan 9, 2013 at 16:53
  • It does appear as if the missing 's' at the end of 'default' would be the cause of your problem. Commented Jan 9, 2013 at 16:59
  • Yea that fixed it. Should I let the question stay? There are other answers. In stackoverflow this questions like this are okay. Deleted questions may make everyone look bad. Commented Jan 10, 2013 at 2:32

    Don't delete it. SOmeone might stumble over this and he or she could use that information :) Commented Jan 10, 2013 at 18:47
  • Mark this as answer. But look at my comment to mdpc's answer. You should not use auto. Commented Jan 10, 2013 at 20:24
